Cross-Density Cartridge Processing - Oracle StorageTek T10000 Operator's Manual

MIR directory information is still completely valid. After a write takes place, the RFID
is marked write-invalid meaning the MIR directory information on tape is invalid.
The T10000 drives use the drive-resident copy of the information to access customer
data pointers for read-only functions. Statistical counters are continuously updated in
the memory-resident information with any drive activity.
When the cartridge is unloaded as part of the unload routine, the drive-resident
information is written to the cartridge's RFID and the tape-resident MIR with the
closed state indication set.

Cross-Density Cartridge Processing

Whenever a data cartridge is loaded that was written in a data density format that is
different from the one used when the drive writes, model-specific MIR processing
occurs. In an environment with mixed T10000 drive models, a mandatory firmware
update provides the capability for the lower-density drive to read the RFID of a
higher-density drive.
For a native data cartridge or Sport cartridge written by a T10000A drive, the:
RFID can be read or updated by a T10000A, B, C, or D drive.
■
MIR can be read by a T10000A, B, C, or D drive.
■
MIR cannot be updated by a T10000B, C, or D drive.
■
T10000A, B, C, or D drive counters can be updated after appropriate firmware
■
updates are installed.
Cartridge can be reclaimed by a T10000A or B drive.
■
For a native data cartridge or Sport cartridge written by a T10000B drive, the:
RFID can be:
■
– Read by a T10000A, B, C, or D drive.
– Updated by a T10000B, C, or D drive.
MIR can be read by a T10000B, C, or D drive.
■
MIR cannot be updated by a T10000A, C, or D drive.
■
T10000B, C, or D drive counters can be updated after appropriate firmware
■
updates are installed.
Cartridge can be reclaimed by a T10000A or B drive.
■
When the T10000A or B drive identifies the data cartridge
Note:
as an unreadable-density data format, it displays 3215 on the
Virtual Operator Panel (VOP) or the physical operator panel of the
rack mount drive.
For a native data cartridge or Sport cartridge written by a T10000C drive, the:
RFID can be:
■
Read by a T10000A, B, C, or D drive.
–
– Updated by a T10000C or D drive.
MIR can be read by a T10000C or D drive.
■
MIR cannot be updated by a T10000A or B drive.
